Alien Bases on the Moon
From supposed towers and hangars to claims of hidden installations on the lunar far side: a guide to the lunar-base theory, its origins and the images often cited in support.

Solar System & Hidden Presence.
A field archive of alleged alien presence on the Moon and other worlds, possible life in the Solar System, ancient-visitor claims and theories of extraterrestrials living among humanity.
Open-source review
The Solar System and Earth
Claims labelled by evidence level
00 / The briefing
Worlds beyond the ordinary record.
This archive explores two overlapping questions: whether life might exist elsewhere in the Solar System, and why claims of hidden alien bases, ancient visitors or extraterrestrials living among us continue to circulate. The cases range from scientifically grounded astrobiology to cultural folklore and unsupported conspiracy theories.
Editorial rule: a real observation is not automatically proof of an extraordinary explanation. Each file distinguishes established facts, witness or image reports, hypotheses and speculation. No extraterrestrial life has yet been confirmed, and no credible public evidence establishes that aliens live secretly among humans.
How to read the archive
Documented: supported by primary records or repeatable observations. Scientific hypothesis: a testable possibility, not a confirmed discovery. Reported: a claim attributed to a person or source. Speculation: an interpretation not established by the available evidence.

The Hollow Moon Theory
Why some claim the Moon is hollow or artificial, what Apollo seismic experiments actually measured, and how to separate a memorable phrase from a scientific result.

The Moon That “Rang Like a Bell”
The famous Apollo-era phrase, what the experiments were designed to measure, and why seismic ringing should not be mistaken for proof of a hollow spacecraft.

The Face on Mars
The Viking image that appeared to show a monumental face, the higher-resolution images that followed, and how pareidolia shaped one of the best-known Martian mysteries.

Ancient Civilisations on Mars
From “pyramids” and city grids to claims of a vanished Martian culture: what anomaly hunters see, what geology can produce, and what evidence would be needed to establish a civilisation.

The Phobos Monolith
A large angular-looking feature on Mars’s moon Phobos has inspired claims of a marker, tower or artificial object. Here is what the image can and cannot tell us.

Europa: An Ocean Beneath the Ice
One of the most scientifically credible places to search for life in our solar system—and why a potentially habitable ocean is not evidence of an alien civilisation.

Enceladus: Plumes, Oceans and Possible Life
Cassini found water-rich plumes, salts and organic compounds at Enceladus. Could life exist there? The evidence makes it a serious scientific target, but not a confirmed inhabited world.

Venus: Life in the Clouds?
Could microbial life survive high in Venus’s atmosphere? A controversial phosphine claim revived the debate, but no finding has established life in Venus’s clouds.

Titan: Methane Seas and Exotic Life
Titan has lakes and seas of liquid methane and ethane, a thick atmosphere and complex organic chemistry. Some speculate about unfamiliar forms of life—but none has been detected.

Could Microbial Life Exist on Mars?
Mars once had rivers, lakes and potentially habitable environments. This is the strongest scientific question in the solar-system alien debate: could microbial life have emerged there, or survive underground today?

Ancient Visitors to the Moon
Claims that ancient texts, monuments or unexplained lunar features record alien visits to the Moon are popular in alternative history. This file separates cultural stories from testable historical evidence.

Aliens Living Among Us
The idea that extraterrestrials walk among humans appears in UFO folklore, science fiction and conspiracy culture. Explore the main narratives—and what evidence would be needed to substantiate them.

Reptilians, Shapeshifters and Hidden Rulers
A prominent modern conspiracy theory claims reptilian beings disguise themselves as humans. Trace its popular history, examine the kinds of “evidence” cited, and learn why the claim remains unverified.

Men in Black: Visitors, Agents or Urban Legend?
Stories of strange, intimidating visitors who warn UFO witnesses to stay silent became a major part of UFO folklore. Explore the original motif and the distinction between documented events and later embellishment.

Ancient Aliens and the Origins of Humanity
Did extraterrestrials influence ancient monuments, technology or human origins? A guide to the claims, the evidence often cited and the archaeological context usually missing from popular retellings.

Are UFOs Proof of Alien Visitors?
Unidentified anomalous phenomena are real as reports of observations that remain unresolved. The harder question is what they represent—and whether any demonstrate extraterrestrial technology.
Open case file ↗03 / Research method
What would count as evidence?
For an extraordinary claim to become a reliable finding, researchers need more than a striking image or an anonymous account. Strong evidence is traceable to its origin, independently reviewable, consistent with the full context and open to testing by other investigators.
Source trail
Start with primary material
Look for original mission imagery, technical reports, transcripts, dated documents and peer-reviewed studies.
Analysis
Check alternative explanations
Test lighting, perspective, compression, natural geology, ordinary aircraft, sensor limitations and the possibility of mistaken interpretation.
Editorial standard
Keep uncertainty visible
An unresolved observation should remain unresolved until the evidence supports a stronger conclusion.
NASA states that extraterrestrial life has not been discovered and that there is no evidence UAP are extraterrestrial. That does not prove life cannot exist elsewhere; it describes the current state of verified evidence.
Video library / Watch the evidence
Videos, mission footage and investigations.
Use these videos as supporting material, not as proof by themselves. Official mission footage documents scientific observations; documentaries, interviews and conspiracy-theory videos present interpretations that should be checked against original records and independent evidence.
